Alternative seating for young children with Autism Spectrum Disorder: effects on classroom behavior.

Schilling et al. (2004) swapped regular chairs for therapy balls in a preschool classroom. They used an ABAB reversal design with young autistic children.

Each child served as their own control. Chairs came back, then balls came back again. The team tracked engagement and staying seated.

When therapy balls were in, kids stayed seated longer and joined activities more. The change was large and immediate.

Removing the balls made the gains disappear. Bringing them back restored the gains. The pattern showed the balls caused the improvement.

Krombach et al. (2020) ran the same idea in homes during ABA sessions. They also saw more attending and sitting. The result repeats across settings.

Brennan et al. (2021) extended the work to clinic preschool rooms. Again, ball chairs helped on-task behavior. The effect holds for kids under six in three places: classroom, home, and clinic.

Ghanouni et al. (2017) and LeBlanc et al. (2003) warn that autistic children wobble more when they look at faces or when lights change. Therapy balls demand constant small balance fixes. The ball studies turn the wobble weakness into a strength by giving kids a built-in movement outlet.

You can boost engagement and cut out-of-seat behavior tomorrow by trading chairs for therapy balls. No extra staff, no tokens, no data sheets needed. Start with one table during art or circle time. Watch for rolling or bouncing that gets too big; mark floor spots with tape so balls stay put. If it works, expand to other tables or centers. The evidence is now backed by three single-case studies across classroom, home, and clinic settings.
